JOHN C. CROWLEY, OF CLEVELAND HEIGHTS, OHIO, ASSIGNOR TO THE DELL MANU- FACTURING COMPANY, OF CLEVELAND, OHIO, A GORORASQN GF OHIO VALVE INSIDE Application filed March 16, 1929. Serial No. 347,459.

The present invention relates to valve insides which, as is well known, are intended to be inserted within a valve stem commonly used in connection with air inflated tubes, such as inner tubes for automobile tires and the like.

An object of the present invention is to provide a valve insides in which the air passageways through the valve insides are greatly increased over vany form of valve insides heretofore known.

Another object is to provide a valve insides in which a part of the body member of the insides may be positioned in a valve stem by an axial movement of said part into the stem and in which said part forms the sole supporting means for the valve pin and valve pin spring, wherefore these elements are not subjected to any twisting or straining action while the valve insides are being positioned in the valve stem.

Another object is to provide a valve ins' les which is soconstructed that the valve is more efficiently guided and, in addition, permits of the use of a smaller valve pin, thus increasing the size of the air passageways through the valve insides.

A. further object is to provide a valve insides which is more compact, simple in construction and more economically manufactured.

Additional objects and advantages will appear hereinafter.

Reference should be had to the accompanying drawings forming a part of the specification in which,

Fig. 1 is a sectional view through the valve insides.

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1. V

Fig. 3 is a top plan View.

Fig. 4 is a. view similar to Fig. l but showing a slightly modified form of construction.

In the present disclosure it will be understood that the valve insides are intended primarily for use inconnection with the standard and usual form of valve stem which is, at present, used in connection with inner tubes for tires, although the use of the valve insides is not restricted to this precise application or use. The standard valve stem needs no description on account of its universal use, but it may be stated that the standard valve stem has an inner bore which is threaded at the outer end thereof for the purpose oi receiving the threads upon a valve insides. rlho bore of the valve stem provided at a short distance from the threaded end ot the stem with a reduced portion which forms a shoulder against which a suite-bie packing member on the valve insides engages for the purpose of effecting an air tight-seal and thereby preventing the escape of air around the body of the valve insides.

The body of the valve insides is formed of' two parts, namely, part l and part 2. The part l is provided with exterior 'threads 5 and adjacent its lower end a ald-.inwardly extending flange t is provided with an i nturned part 5. The part l is provided with a @entrai passageway or bore having an enlarged portion G for a part of the length of the bore and a portion 'l' of slightly less diameter for the remaining length of the bore, this latter portion be ing adjacent the outer end of the part l. rihe outer end of the part l is also provided with recesses 8 which extend outwardly toward. the edges of the part l and are diam ctrically opposite, the purpose of such recesses being to receive a wrench when the valve insides are being positioned in a valve stem. rthe other part of the body member is formed adjacent its upper end with an outtu`1 l flange 9 spaced from another outwar l. extending fia-nge 10. Between these fir` there is, therefore, an annular recess ll within which the inwardly extending part of the flange 4 on the body member part l extends, so that the part may be said to lie between the ianges 9 and 10. There is eiiiected a swivel connection between the two parts oi the body member with thc result that the part 2 may be inserted into a valve stein an d forced longitudinally into proper position therein by hc rotation of the part l, the 'g rior threads fl of which engage the in threads of the valve stem. In other words. the part 2 merely has an axial movement into the valve stem, while the part l positioned therein by rotating movement. Beyont` the flange A a recess 12fis formed in the body member-tor the purpose of receiving asuitablepacking member 13 which cooperates with the valve Vstemto form an'air-tight connection. The lower end of the vpart 2 is externally tapered so that the lower edgeofsuch part, indicated at 14, forms a relatively narrow valve seat.`

1,V such upwardly extending portion lobeing provided atitsupperf end withan inturned portion 16,` which entends part of the'way i across the bore in the part land is provided 'with ai relatively small opening V17 concentric with the bore through the part 1'. `Thereis,

of course, a central air passageway or bore'lcl through the part 2 of the body member, which passageway; is concentric with the passageway inr the part 1. It will be seen that the `nassageways 18 inthe Vpart 2 and tliepassage` vwayin the part 1 formed ot'vtheportions e' and 7 provides maximum air passageway through the valve insides and that the in-V turned portion 16; of th'epart 2 otfers a minimum restriction to such airpassageway,v

` tending through Vthe air passageways the V,valve pin 19 has at its upper end an annular head 20, while its vlower vend is connected to a valve member 21 which cooperates with the "valve seat 11i on thepart 2. The' valve pin 19 `'entends through the opening 17 in the in-' f turned portion16,while a valve spring 22 arranged on the pin between the head 2O and the inturned portion 16 of the body member tends to normally force the pin inwardly and to causeV the valve member21 to engage 'Y its seat 14. f

f In both 1 and the valve member 21 is disclosed vasl formed in the nature of a cup-'shaped member which `has pac-king 28 in the `cupportion thereof. However, in..

Fig. 1, asleeve 2st extends axially through the valve member A21 and the packing 23, such sleeve being provided at its upper end above.

` the valve member with an enlarged so-called Y ball portion 25, the tapered sides of which engage the lower edge ot the part 2' of the body member when the valve member 21y is moved into and out of seating position. vIn

. j the form shown in 1 thevalve pin 19 has its lower end secured in the sleeveinember-24 and since the ball'25'is carried bytliesleeve member the resultis that a smaller diameter valve pin may bel used than is possible inthe ordinary form of-construction wherein the `ball`25ci is formed on the valve pin as shown in Fig. 4, while thelower'end ofthe valve Vpin extends through the'valve member.` It

will be noted that the valvey pin is guided at 2 points, namely, by the inturned portion V16 of the body member part 2'and byy thel valve member 21. In addition to this uncn tion of the inturned portionv 16 thesame'also 1,829,556 A` I i n f serves as the lower abutment for the spring Y, 22,.v It should further be noted, ask already mentioned, that the inturned portion 16 oiers minimum obstruction or restriction to the air assaeewa sV through the valve in- I) 42: l r#o sides.l l

Arturtherand very important consideration` resides in the tact that when the valve insides are being assembled in the valve stem jiio'twisting or straining action will-.be imparted to the valvep'in or the valve spring 22 since these elements are carried solely by the body member part 2 andthe valve mem-v ber 21, which members do not rotate but are forced axially into the valvestem bythe rotation oi ythe.,bodymember part 1. Also should be notedthat the provisionof the inturned portion 16, whichV might `bete'rmed a member, intermediate the ends of the` body member. results in a more compact Aand simple arrangement and is also capable ot beine' more economically produced.

. should be 'understood thatthe invention is siisceinible.l of various 1modifications andv adaptations within the scope of the appended claims.

"Having .thus describediny invention, I claimt 1 zj Y Y 1.
